FoodNet employs a systematic approach to data collection. It uses active surveillance, meaning that public health officials regularly contact clinical laboratories to identify new cases. This contrasts with passive surveillance, where data is only collected from reports that are voluntarily submitted. The active method ensures more comprehensive and accurate data. Additionally, FoodNet collects data through periodic surveys and studies to gather information on food consumption habits, healthcare-seeking behavior, and other risk factors associated with foodborne illnesses.
